Just started last week but several times now when I'm cruising and decide to downshift to second and "wind it out", when I reach the redline and shift into third it will not go in gear. Still pretty much stock except for what's in my sig. Regular maintenance and oil changes (Mobile 1) No issues at all when shifting normally. There's no knocking or mashing sounds. It drives as good as it always has but for this new shifting problem. If I'm running thru the gears on the hwy it still shifts ok. I have a little over 20K miles and up to now never one single problem with shifting under load. Anybody else?:eek:

I get the 3rd gear grind when it is cold until it warms up a bit. I have been locked out of 3rd once or twice but it hasn't happened in a while. 2nd sometimes feels notchy when I downshift into it. I didn't have any problems shifting when driving on the Barber road course recently. I am at about 13K miles.

I have been locked out of 3rd at high rpm's several times. I find at high rpms I have to make a conscious effort to make darn sure I put it exactly in third or I'm going to have a problem. It seems like at a high rpm the "gate" is very exact (narrow?) and easy to miss, if that makes any sense.

Also, yes, my tranny is very stiff when it's cold but it will be ok once it's warmed up. This seems like a separate issue and one I've had with other cars (mustangs) in the past.

stock shifter?
Yep it's stock. I've been shifting fine during redline gear changes for the past year and 4001 never balked once. I know the "fly by wire" shift mechanism the S197's employ have sometimes been prone to this. There's an article in MM&FF's (July '08 Pg 140) about how the aftermarket addressed this issue with a stouter Throw Out Bearing/Slave Cylinder. I was just wondering if any of you guys had experienced third gear lock-outs when really getting "on-it". Here's a couple links on the issue...

They aren't cheap. I'm nowhere needing a clutch so I'm hoping new brake fluid, a flush & bleed might help...I dunno?

Have you tried double clutching to help any on the downshifts?

Those articles seem to indicate that this is a function of the hydraulic system's flow capability. How are you depressing and releasing the pedal?

The "fly-by-wire" piece of the equation is oriented to the throttle plates opening and closing in response to gas pedal pressure. I don't believe there is a direct connection between that and the clutch action.

Update Ford TSB 09-9-6 Issued May 1st 2009

While researching my shifting problem I came upon a recent TSB by Ford covering the replacement of the 1-2 and 2-3 (me) sychronizers. I knew I wasn't crazy...hold onto your pants boys.

That is kind of funny, after you check to make sure the floor mat is not in the way, what is the next step? Why pull the tranny out of course. I just figured they'd have some other tests before that drastic of a step. I've had mine grind going into 3rd once when it was fully warm, the other handful of times they were all at or below 40*F. I don't know if I want them pulling the tranny because of this happening every now and then but I don't want it going completely out 6 months after my warranty runs out either. Does anyone know if the new synchro's are updated or if any of the replacement parts are? Or are the stock parts defective? Doesn't make sense to replace them with the same thing unless something wasn't put together right or they updated the part.

Wheelman,

I have the exact same problem. Shifts OK regular driving but not at high RPMs. Only 2nd to 3rd shift problem. It started at the Mustang 45th Anniversary Celebrations, with only about 4,500 miles on the odometer. I had the car on the track. The first 2sessions on the morning had not problem. The first session of the afternoon, coming out the hairpin turn in second gear, revved up to 5500 RPM, went for 3rd gear but it wouldnt go in. No grinding or clashing, justlike hitting a stop. Went around the second lap and same thing happened. Of course I had an instructor for that session... What an embarassment. Blamed it on nervousness, not holding the shifter right, not guiding it through the gate. (Frankly if my car has a transmission that is so finicky that shifting gear becomes a manual dexterity exercise, I will get rid of that car). Tried the next session and same thing. This time I made sure there was no traffic and made a very deliberate shift - no go. Finished the day in 3 - 4th gears.

I had a Hurst shifter at Barber Motorsport Park. I relaced it with a MGW which claims to have a solution to this problem. Two days ago I wound it up in 2nd gear, went for 3rd - hit the block again...

Has to be the transmission. But how do you convince the delearship to fix this problem? Intermittent problem, and only at high RPM and only when the car had a real workout, such at track time.:rolleyes:

Don't worry, dealership's regularly fix warranty issues. That's one of the main reasons for their service department. Copy the TSB I posted above and take it with you to the Ford dealer. Shouldn't be a problem at all. I'm calling my dealer's service department Monday to make an appointment. They'll replace the parts they need to and voila .... problem fixed. "Knock-on-wood" lol:lol:

I am looking forward to hearing your feedback. I took mine in for the same due to cold temps. I left it for the trans tech to drive but never could recreate the problem. I was told it needs to warm up. He said if the syncros are going bad it will happen regardless of the temps. I have decided to wait this one out.

I had 300 miles on my Bullitt when the dealership replaced my transmission. I was in a mustang cruse , I was having a Bullitt moment when 3rd just disappeared on me ! After that my car would grind every time I went for 3rd gear.
If I would of had more miles on my car they would of just replaced the syncros.

Update...The Road To Repairs

I begrudgingly took 4001 back to my Ford dealer yesterday. To my surprise the service manager couldn't have been nicer. He even went so far as to page the transmission specialist and let me talk to him. After describing my problem he knowingly smiled and said he didn't even need to drive it. They have all the parts on the TSB on order (having that TSB with me was the key) and will call me as soon as the parts get in. Couldn't be more pleased
........ so far!

Well well well. The 3650 raises it's ugly head yet again. I am at a loss as to why Ford thinks this is a GOOD transmission. Sorry to say we 01 owners have had similar issues with this tranny as well. According to Tremec it was "fixed" on the new model of trans. In my case to deal with the transmission, I had to re learn how to shift. When shifting at high RPMs I found palming the shift ball and pushing straight up helps. If you try to force it into gear you will miss 3rd every time. I have an aftermarket shifter and it still is an issue. See here: http://www.imboc.com/forums/search.php?searchid=581796&pp=20

Luc, I remember you telling me about this problem at Barber. I didn't have problems coming out of that hairpin hard from 2nd all day.

How does your GT500 shifter and tranny compare? I think it is the same Tremex used in the older Cadillac CTS-V, and a co-worker who has one complains about his locking out gears too.

'05 GT same exact problem - traded it in on my Hummer - wife got the hummer - bought #5611
have 3K miles now - same problem - have appointment next tuesday at Soerens Ford in
Brookfield,WI The tech there ( Chris ) is a fanatic when it comes to Mustangs - Plan on
taking the TSB with me & let him take care of the problem - he's more anal retentive about
Mustangs than I am - I'll keep ya'll informed

Thought at first it was just one of those senior moments, but not the same issue on two
different Mustangs three years apart.

Be interesting to see how this turns out.

Reads like you have the right Tech going to look at the situation for sure.
